«Karski's exploration of the moral fog in which he and his colleagues operated ... made me recall thrillers like Man Hunt and Hangmen Also Die ... two episodes resemble scenes tantalisingly directed by Hitchcock ... Karski's account of the systematic brutality of the Nazi regime is literally chilling»

Peter Conrad, The Observer

«Reads like the screenplay to an incredibly exciting war movie - but it is all true»

Andrew Roberts

«Seared with an urgency that pitches the reader into the heart of the horror»

Ben Felsenburg, Metro

«His story deserves not just revival but reflection ... Karski's electrifying words still speak only too eloquently for themselves»

Marek Kohn, Independent

«Jan Karski's Story of a Secret State stands in the absolute first rank of books about the resistance in World War II. If you wish to read about a man more courageous and honorable than Jan Karski I would have no idea who to recommend. Yes, it's that good.»

Alan Furst

«It deserves its status as a Penguin Classic, not only because it is a great historic document, but also because it's a cracking good read: Karski's adventures are worthy of the wildest spy thriller»

Nigel Jones, Telegraph

«His account of his missions is an electrifying tale of false identities, near captures, spies and secret film capsules ... in human terms, Karski's account is invaluable»

Frank Trentmann, Daily Express

«Story of a Secret State is now viewed as a classic insider's account of the Resistance in occupied Europe...After all the harrowing descriptions of Holocaust horrors there have been over the years from survivors of Auschwitz, Belsen, and Ravensbruck, Karski's vivid account of what he saw back in 1942 is still deeply moving. We feel his shock and incredulity that this could really be happening in 20th century 'civilised' Europe.»

Tony Rennell, Daily Mail

«The bravery of the man who risked all to tell the world about the Holocaust is truly staggering ... an extraordinary testament to Man's inhumanity to Man, and the even more remarkable courage required to resist it»
